- I had a bad experience working there.
Is that sentence correct, or must I write:
- I had a bad experience when working there.
- I had a bad experience while working there.
or even:
- I had a bad experience while I was working there.
- I had a bad experience when I worked there.
It seems like sometimes gerund–participle clauses (meaning -ing clauses) can be directly used in an adverbial way, without any sort of conjunction or preposition joining them to the rest of the sentence.
- Working there, I developed a real sweet tooth.
- While working there, I developed a real sweet tooth.
- By working there, I developed a real sweet tooth.
- I developed a real sweet tooth working there.
- I developed a real sweet tooth while working there.
- I developed a real sweet tooth by working there.
Are there rules governing when you can use a gerund clause on its own like this without a connecting word?
